A thin section through a macrophage from interstitial tissue of the testes of the opossum. These cells are characterized by extensive folding of the cell surface, some of which appear to have captured...

Leishmania mexicana amastigotes in their parasitophorous vacuole in a mouse macrophage. Murine macrophages (cell line J774) were infected in vitro with Leishmania mexicana stationary phase promastigot...

Primary bone marrow macrophages derived from mouse plated on a coverslip and imaged live. Phase contrast microscopy allows us to see the dense f-actin rich leading edge, ruffles, mitochondria, the nu...

Phase contrast microscopy of living bone marrow derived macrophages. These cells are highly motile and the snapshot catches lamella and ruffles where the cells are protruding and phase dense organell...
